Preheat your oven to 400 degrees F. Line a baking sheet with a silicone mat or parchment paper.
Place pizza dough on a floured surface and form into a ball. Cut the ball into 4 equal pieces. Flatten the pieces into 4 x 5-inch rectangles. Use a knife or pastry cutter to cut each rectangle into 4 long strips, and then cut long strips in half.
To make the knots, take a small strip of dough and roll it into a snake (long and skinny). Gently tie the dough into a knot. Place dough knot onto your prepared baking sheet. Repeat with the rest of the dough placing knots about 1-inch apart.
Bake for 15 minutes or until the knots are golden brown.
While the knots are baking, make the garlic butter. Melt the butter for about 30 seconds in the microwave. Stir in garlic powder, dried oregano, and dried parsley.
Carefully remove knots from the oven. Immediately use a pastry brush to coat the knots in the garlic butter mixture.
Sprinkle on some grated parmesan cheese on top of the knots too. If the cheese doesn't melt on its own, you can pop the baking sheet in your warm oven for a few minutes. This will brown up the knots a little more thanks to the butter.
You can serve these garlic knots warm or at room temperature. I like to serve them with a bowl of marinara sauce for dipping.
If you want to make bigger knots to serve as a side dish with dinner: Instead of cutting the dough rectangle into 8 pieces each, cut them into 3 or 4 pieces. Then roll the dough snakes and tie them into knots. After that, proceed as directed.
